you can see a mist of fuel comming out of the air filter. ill have to do a better job proof reading my posts..

Start checking the 3 things needed: Air, fuel, ignition. Take out the plugs, are they wet with fuel, hook them to the ends of the wires an lay them on the head or other ground, see if there is spark. Run A compression check.

o.k. thanks shovelmike, i dont have a compression tester. ill try to find one cheap. plugs were dry but had blk. soot all over the outer edge. this is going to be one of those paaaain in the ass projects..

Buddy of mine had a similer problem while on a trip. Brought the bike to the dealer and they found a slight break in a connection due to going over some railway tracks. No money for parts needed, just a little time.
I'd start with all your connections. By any chance did you just wash your bike when it started acting up?

Good luck.

mafosa · 10-24-2009, 08:13 PM

no. no new changes. been riding on the feul for a couple of days. plugs are a couple week old. changed them anyways. im going to start with check for spark thing. thanks for your input BIG-G
i hate trouble shooting!

.. getting spark. is there a fuel filter in there? how can i do a fuel pressure test?

Antonio Pendejo · 10-24-2009, 10:13 PM

It would be a benefit to all reading this post if you could be a little more decriptive of your bike. What year, fuel injected, yes I got that by reading your tag line. I can also see by your vid that it is some softail model. The very first thing is to unplug the powercommander and see how it behaves.
After that I would be checking for leaks in the in-tank fuel lines. Is the check engine light coming back on after you try to start the bike? Leaky in-tank fuel lines will not normally show check engine codes.
There was also a problem with the fuel filter on 07 or 08 models, the filter housing would crack causing symptoms like yours.

I noticed on your video the sound of the fuel pump running after the bike quits, and seems to run longer than normal to build up pressure. I think I would start with checking the in-tank lines. My .02 cents worth.

As far as checking pressure, Harley has a special adapter for that. Maybe someone else knows of a good, cheap way to do it.

hey thanks fellas, its to late to start this project. my work week starts sun. i too was thinking it was a fuel del issue. the bike doesnt want to start at all now. during the week im going after that fuel line inside the tank. thanks again on all your input.
side note: i did notice the fuel pump sounded different to me. thanka again..

I went back and reviewed your video again. Defenately a problem inside the tank, sounds like fuel spray. Time to pop the canopy off the tank and get elbows deep into it. What year bike? Still have a warranty? If milage and age are not too great this may fall under the extended emissions warranty, just something to think about.

o.k. heres what i got so far. this is a bitch.. im not sure if i pulled this out or if this was the cause. the regulator housing tab is bent. the o-ring is rould out. im going to get the new housing. i cant get any of the other stuff out. i gave up for the night. one piece fell into the tank and i cant get it out. the fumes got me gitty.. by the way its a 06 fuel injected. no warrenty (where it.) thanks again for the help.

I don`t know if you or the person replacing your plugs a couple of weeks ago applied anti sieze to the plug threads, but I had a stalling problem which after a lot of checking, turned out to be caused by the anti sieze compound...I had put a little too much on the threads and some of it was on the end of the plug. This stuff conducts electricity and it was shorting the spark. This may not be your problem but.....

Make sure you change the gasket and the screws on the tank because they will leak.

The pump is actually on a spring loaded hinge its tricky to get out but once you do its easy to re-install. You have to disconnect the supply line first,I cant tell in the picture if you did.
